Los Angeles based tuner Royal Muffler introduced this stunning project based on the Porsche 911 GT3 RS. The car is wrapped in satin grey and satin white to make the main stripe while the main livery is satin blue. The Porsche 911 GT3 RS (type 997) is already a race car for the street but R1 Motorsport took the concept even further by installing a lighter carbon fiber rear from the GT3R Hybrid in order to keep the weight down.

Power still comes from the 3.8 liter flat-six producing 450 hp. The car rides on center lock BBS Wheels wrapped in TOYO R888 tires and the original ceramic brakes were dropped in favour of Brembo Type III 2-Piece Floating Discs for track use. More high res pictures of the beast in the gallery below.
